摘要:
The visual function inspection system of the present invention is different from the first shape information indicating a plurality of different shapes of the target portion included in the optotype and/or the glare portion included in the optotype at a position within the visual field of the subject. Storage means for storing second shape information indicating a plurality of shapes; and a shape of the portion of interest and/or the glare portion based on the first shape information and/or the second shape information according to the purpose of the visual function inspection. Of a plurality of light sources and at least one light source used as a glare portion in the visual function inspection among the plurality of light sources and the position thereof are determined in the visual function inspection. Any one of the determining means A2 configured to determine according to the purpose, the brightness contrast value between the brightness of the target portion and the brightness of the background portion, and the visual target including the target portion and the background portion. Of the luminance average value and the stimulus value of the color stimulus of the visual target, the visual function inspecting means sequentially presenting to the subject a different visual target, and based on the inspection result by the visual function inspecting means, In a coordinate system showing the correlation between the brightness contrast value and the brightness average value, for each combination of the stimulus values of the color stimulus, determining the boundary between the region where the subject has visibility and the region where the subject does not have visibility. According to the above, the analysis means for determining at least two of the boundaries is provided.本発明の視機能検査システムは、視標に含まれる注目部分の互いに異なる複数の形状を示す第1形状情報及び/又は被験者の視野内に入る位置で前記視標に含まれるグレア部分の互いに異なる複数の形状を示す第2形状情報を記憶する記憶手段と、視機能検査の目的に応じて前記第1形状情報及び/又は前記第2形状情報に基づき前記注目部分の形状及び/又は前記グレア部分の形状を決定する決定手段とから構成される決定手段A1、
